I am using a Porter Cable 4" x 24" belt sander to finish my timbers. The problem I'm having, is that the belts keep breaking. I do my best not to push down on the sander. I'm using 3M, 100 grit belts. Does anyone else have this problem? What do you all recommend using for belts? Continuous use just seems to heat up the platen and belt too much. Comments....
